This book presents an overview of graphene from rationale to applications, including basic concepts, theories, and principles. Hereinto, preparation methods, growth mechanisms, condensed matter structures, and graphene chemistry are described in detail. The book emphasizes electrical, optical and magnetic properties of graphene. Subsequently, the prospects and challenges of graphene in composite materials, energy materials, and industrial applications are systematically introduced. This book can be used as reference for senior undergraduates, postgraduates, and institute researchers in the fields of chemistry, materials, physics, and information.

Graphene is an ideal two-dimensional atomic crystal composed of monolayer carbon atoms, which has broad application prospects in the novel electronic devices, such as nanoelectronic devices, integrated circuits, flexible electronic devices, and ultra-sensitive sensors. This book covers the structure, physicochemical properties, preparation techniques, characterization methods and potential applications of graphene. This book can be used as an introductory book for researchers working on graphene research, especially for beginners.

The book is aimed to commemorate the establishment of the chemistry prize of the youth for 30 years. The winners of the chemistry prize of the youth set a good example for young chemists. This book has included the speeches of 48 winners during the period from the year of establishment to 2012, where we can appreciate the growth process of a generation of chemical people. Also, we can learn the contribution of scientific research and innovation by these prize-winners as well as the enlightenment, experience and realization from practice. In addition, expectations and messages to the young scholars are included in this book.

This book is designed to enhance communication between tutors and students and provide new ideas for teaching, which can further improve the quality of education in the Institute of Chemistry. Based on the experience of Institute of Chemistry Chinese Academy of Sciences, the book is supposed to describe lessons from training students. The whole content is divided into two parts. The former for tutors  records the experience, achievements, lessons in graduation education over years. The latter for students describes school life in Institute of Chemistry Chinese Academy of Sciences, providing useful suggestions for students.

Molecular devices are ordered structures assembled by single or few functional  molecules with optical, electrical, ionic, magnetic, thermal, mechanical, and chemical-reactive characters. They are physicochemical systems, which can realize detection, conversion, transmission, storage, and of information and energy at the molecular level. In short, molecular devices are ultramicroscopic devices with specific function.

On December 21, 2001, "Science" (American journal) voted on top tem progress of all sciences in 2001. Among them, "Molecular get wired" stood out, which literally means "connecting molecules". It marks the beginning of molecular electronics researches from molecular materials and devices and then turning into molecular circuits. Molecular electronics use single molecules in information processing devices and demonstrate the corresponding mechanisms, the research level of which include molecular materials, molecular devices, molecular circuits, and molecular computers. Molecular materials are organic or biological materials applied to make new information and microelectronic components.
